SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 400,362, dated March 26, 1889.

Application filed May 16, 1888. Serial No. 274,058. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM STEVENSON RoUNDs and HORACE O. ROUNDS, both of Townville, in the county of Crawford and Stateof Pennsylvania, have invented a new and useful Improvement in Side-Bar Springs for Vehicles, of which the following is a full, clear, v and exact description.

Our invention relates to an improvement in side-bar springs adapted for use in connection with side-bar vehicles of every description, and has for its object to provide a cheap, simple, durable, and economical spring, and wherein the body of the vehicle may be hung low, and also wherein the spring will be a noiseless one and communicate a pleasant and easy motion to the body.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,.

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a bottom plan view of the spring, and Fig. 2 is a transverse vertical section on line a: 00 of Fig. 1, the spring being inverted. Fig. 3 is a longitudinal vertical section.

It has heretofore been the practice to make springs heavier at the back or rear end of the vehicle than at the front end, the greater burden of the load being usually back of the center. By this means the springs are rendered unnecessarily heavy, frequently indicating a lack of symmetry. To overcome these objections and produce a symmetrical, light, durable, and eifective spring is the prime object of the present invention.

To this end A and A represent, respectively, front and rear body-bars, and B B the springs adapted for attachment to said body-bars and the side bars. The springs B and B are preferably constructed of rod metal, essentially bent to a U shape, the members whereof at their extremities of the U shape are carried at right angles outward in opposite direction to form the supporting-arms b b and 19 D The said arms after leaving the body of the spring are carried downwardly and upwardly, as

shown at O in Fig. 2, and are provided at their extremities with, an eye, d.

A horizontal plate, D, purposed to be secured to the side bars, is pivotally attached to the eye of the several spring-arms by means of downwardlyextending lugs 01, integral with opposing edges of said plate, and a bolt, d passing through the plate lugs and eyes, as shown in Fig. 1. The bow end of the spring B is held to turn in bearings E, attached to the inner side of a rear body-bar, and the members of the body at the opposite end are journaled in bearings E, secured to the under face of a front body-bar, as best shown in Fig. 1. The arms b and b are thus made to extend outward parallel with the bar beyond the ends of the same, as illustrated in Fig. 2. The second spring, B, is held to turn in bearings E attached to the inner side of the front bodybar, and the members extending parallel with and outside the members of the spring B are 'journaled in bearings E secured to the under face of the rear body-bar, the arms I) and b being made to extend outward from the bar in a similar manner to the aforesaid arms b and b.

The rear arms, b and b being adapted to support the burden of the weight, are made shorter than the front arms, whereby they are given additional strength. In order, therefore, that the plates D, carried by the front and rear arms, may be in the same plane, the bearings E -are located a suitable distance nearer the ends of the rear body-bar than the similarbearings, E, secured to the front bodybar. It will thus be observed that when the weight of the body is brought to bear upon the. arms they will in turn exert a torsional strain upon the springs, by reason of which the said body will receive an easy and pleasant motion free from any sudden jar or jerks.

In order to avoid any unpleasant noise or loose play, We line the bearings with leather or other equivalent material.

We desire it to be understood that the several sections of the device may be constructed in straight or curved lines, as desired.

Having thus described our invention,what we claim as new, and desire to secure by Letters Patent, is-

The combination, with the front and rear b0dy-bars,-of U-shaped springs, each secured to the inner face of one bar and to the under face of the other bar and provided with outwardly projecting arms, the arms of one spring being longer than the arms of the other,
